Intraventricular hemorrhage (IVH) is a frequent complication of prematurity that is associated with high neonatal mortality and morbidity. IVH is accompanied by red blood cell (RBC) lysis, hemoglobin (Hb) oxidation, and sterile inflammation. Here we investigated whether extracellular Hb, metHb, ferrylHb, and heme contribute to the inflammatory response after IVH. We collected cerebrospinal fluid (CSF) ( n = 20) from premature infants with grade III IVH at different time points after the onset of IVH. Levels of Hb, metHb, total heme, and free heme were the highest in CSF samples obtained between days 0 and 20 after the onset of IVH and were mostly non-detectable in CSF collected between days 41 and 60 of post-IVH...

We report diffusion tensor tractography (DTT) of the corticospinal tract (CST) in a patient with paresis of all four limbs following subarachnoid hemorrhage (SAH) with intraventricular hemorrhage (IVH) after the rupture of an anterior communicating artery (ACoA) aneurysm rupture. The 73-year-old female was admitted to our emergency room in a semi-comatose mental state. After coil embolization-an acute SAH treatment-she was transferred to our rehabilitation department with motor weakness development, two weeks after SAH...

Recent single center retrospective analysis displayed the association between admission computed tomography (CT) markers of diffuse intra-cranial (IC) injury and worse cerebrovascular reactivity. The goal of this study is to further explore these associations using the prospective multi-center Collaborative European Neurotrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) high resolution data set (HR ICU). Using the CENTER-TBI HR ICU sub-study cohort, we evaluated those patients with both archived high-frequency digital physiology (100 Hz or higher), and the presence of a digital admission CT scan...

PURPOSE: Diffuse axonal injury (DAI) is the rupture of multiple axons due to acceleration and deceleration forces during a closed head injury. Most traumatic brain injuries (TBI) have some degree of DAI, especially severe TBI. Computed tomography (CT) remains the first imaging test performed in the acute phase of TBI, but has low sensitivity for detecting DAI, since DAI is a cellular lesion. The aim of this study is to search in the literature for CT signs, in the first 24 h after TBI, that may help to differentiate patients in groups with a better versus worst prognosis...

Background: The incidence of intracerebral hematoma among patients with aneurysmal subarachnoid hemorrhage is up to third of the cases (12%-35%). The presence of an aneurysm with ICH negatively influences the patient's presentation, course, and outcome, and may be associated with an increased re-hemorrhage rate, vasospasm, cerebral edema, and hydrocephalus. Aneurysm obliteration and hematoma evacuation have been associated with a favourable outcome. Aim of Study: To explore the effectiveness and the prognostic factors for patients with middle cerebral artery aneurysm associated with intracerebral hematoma treated by early surgical clipping of the aneurysm with hematoma evacuation...

BACKGROUND: Intraventricular hemorrhage (IVH) and white matter lesion (WML) severity are associated with higher rates of death and disability in intracerebral hemorrhage (ICH). A prior report identified an increased risk of IVH with greater WML burden but did not control for location of ICH. We sought to determine whether a higher degree of WML is associated with a higher risk of IVH after controlling for ICH location. METHODS: Utilizing the patient population from 2 large ICH studies; the Genetic and Environmental Risk Factors for Hemorrhagic Stroke (GERFHS III) Study and the Ethnic/Racial Variations of Intracerebral Hemorrhage study, we graded WML using the Van Swieten Scale (0-1 for mild, 2 for moderate, and 3-4 for severe WML) and presence or absence of IVH in baseline CT scans...

BACKGROUND: Hydrocephalus is a common and major complication that affects outcome after intraventricular hemorrhage (IVH). While aging impacts the occurrence of hydrocephalus in patients with IVH this and the underlying mechanisms have received little attention. The present investigation, therefore, studied the impact of aging on hydrocephalus after IVH in a rat model. METHODS: Young and aged (3 and 18 months old, respectively) male Fischer 344 rats had an intraventricular injection of 200 μl autologous blood or saline...

OBJECTIVE: The amount of extravasated blood is an established surrogate marker for subarachnoid hemorrhage (SAH) severity, which varies in different experimental SAH (eSAH) models. A comprehensive eSAH grading system would allow a more reliable correlation of outcome parameters with SAH severity. The aim of this study was to define a severity score for eSAH related to the Fisher-Score in humans. MATERIAL AND METHODS: SAH was induced in 135 male rats using the modified double hemorrhage model...

Background and Purpose- Definitions of significant hematoma expansion traditionally focus on changes in intraparenchymal volume. The presence of intraventricular hemorrhage (IVH) is a predictor of poor outcome, but current definitions of hematoma expansion do not include IVH expansion. We evaluated whether including IVH expansion to current definitions of hematoma expansion improves the ability to predict 90-day outcome. Methods- Using data from the PREDICT-ICH study (Predicting Hematoma Growth and Outcome in Intracerebral Hemorrhage Using Contrast Bolus CT), we compared a standard definition of hematoma expansion (≥6 mL or ≥33%) to revised definitions that includes new IVH development or expansion (≥6 mL or ≥33% or any IVH; ≥6 mL or ≥33% or IVH expansion ≥1 mL)...

Background: Pneumothorax is a medical emergency and is associated with a significant increase in morbidity and mortality in newborns. It may lead to acute respiratory failure, systemic hypoperfusion, intraventricular hemorrhage (IVH), and death. There is a paucity of data from developing countries about the epidemiology of pneumothorax. Objective: This descriptive study was planned to study the clinical and epidemiological profile of hospitalized neonates with pneumothorax. Material and methods: In this retrospactive study neonates admitted to Neonatal Intensive Care Unit (NICU) from 1 January 2004 to 31 December 2016 were reviewed...

OBJECTIVE: Posthemorrhagic hydrocephalus of prematurity remains a significant problem in preterm infants. In the literature, there is a scarcity of data on the early disease process, when neurosurgeons are typically consulted for recommendations on treatment. Here, the authors sought to evaluate functional outcomes in premature infants at 2 years of age following treatment for posthemorrhagic hydrocephalus. Their goal was to determine the relationship between factors identifiable at the time of the initial neurosurgical consult and outcomes of patients when they are 2 years of age...

The lysis of red blood cells was shown to occur in human ruptured atherosclerotic lesions and intraventricular hemorrhage (IVH) of the brain. Liberated cell-free hemoglobin was found to undergo oxidation in both pathologies. We hypothesize that hemoglobin-derived peptides are generated during hemoglobin oxidation both in complicated atherosclerotic lesions and IVH of the brain, triggering endothelial cell dysfunction. Oxidized hemoglobin and its products were followed with spectrophotometry, LC-MS/MS analysis and detection of the cross-linking of globin chains in complicated atherosclerotic lesions of the human carotid artery and the hemorrhaged cerebrospinal liquid of preterm infants...
